The Super73-S2 also gets a bigger battery. When I reviewed the Super73-S1, it came with a 700Wh battery. But the Super73-S2 now ships with a 960Wh battery. That's enough for around 40 miles (64 km) of real-world range on throttle only use, or even more if using pedal assist.

The Super73 S2 is a Class 3 ebike. You can use the hand throttle to take it up to 20 miles per hour without pedaling and receive assistance from the electric motor up to 28 miles per hour while pedaling. That's because the rear hub motor runs at 750-watt continuous power and 1,200-W peak power.
